Source Note
Name Type DIS DIS format CFG List
BCD2−DATA1 d C1719/2 bin C1718/2 2 Data input (LSB)
BCD2−DATA2 d C1719/3 bin C1718/3 2 Data input
BCD2−DATA3 d C1719/4 bin C1718/4 2 Data input
BCD2−DATA4 d C1719/5 bin C1718/5 2 Data input (MSB)
BCD2−READ d C1719/1 bin C1718/1 2 Only required for handshake mode:
· Signal must be applied at the controller for at least
2 ms.
· LOW−HIGH edge starts the data transmission for a
BCD.
BCD2−LOAD d C1719/6 bin C1718/6 2 LOW−HIGH edge = Write data to the code.
BCD2−BUSY−IN d C1719/7 bin C1718/7 2 Generating a collective busy signal
BCD2−FAIL−IN d C1719/8 bin C1718/8 2 Generating a collective fail signal
BCD2−SIGN d − − − − HIGH = Read sign.
BCD2−SEL1 d − − − − HIGH = Read 1st BCD.
BCD2−SEL2 d − − − − HIGH = Read 2nd BCD.
BCD2−SEL3 d − − − − HIGH = Read 3rd BCD.
BCD2−SEL4 d − − − − HIGH = Read 4th BCD.
BCD2−SEL5 d − − − − HIGH = Read 5th BCD.
BCD2−SEL6 d − − − − HIGH = Read 6th BCD.
BCD2−SEL7 d − − − − HIGH = Read 7th BCD.
BCD2−SEL8 d − − − − HIGH = Read 8th BCD.
BCD2−NEW−DATA d − − − − HIGH = BCD accepted, transmit next BCD.
BCD2−EOT d − − − − HIGH = all BCDs read or "CANCEL" recognised.
BCD2−DATA−FLT d − − − − HIGH = BCD code (see chapter 3.5.12.1).
BCD2−BUSY d − − − − HIGH = Data are being transmitted to code.
BCD2−FAIL d − − − − HIGH = Data transmission to code is faulty.
